The game follows the theme of the classic game marble madness, with a few twists.
The principle of MarBall Odyssey is simple: guide the ball to the exit without falling out of bounds,
avoiding obstacles or by triggering various mechanisms.
Along the route, you can pick up various bonuses to improve your score.
HOW TO PLAY:
While the little tutorial is able to show/learn most of the game mechanics i must admit that a lot of people are playing Marball Odyssey the easy way, which correspond for me : the author, as the wrong way! ;-/
Maybe just because the ‘red exit area’ is always opened, most of the players are simply trying to reach the exit without collecting all the items and then missing the most interesting and challenging part of the game :
Finishing all the levels with ALL achievements!
Which means that you need to find a perfect path to be able to collect ALL rings, extra coins (<- that are hidden first) and big coins!
Then it will open up secret or bonus passages (activating some blue portals) to complete the level with full options, in a race against time!! 
RULES:
collecting all rings will create additional extra coins.
collecting all extra coins will give an extra life on exit.
collecting all big coins will activate a special blue portal and one extra life on start.
Activating a purple checkpoint is giving more time.
Fences can be broken using the big ball or the small ball with high velocity.
bridges can be broken using the big ball.
Yellow buttons can be used only with the big ball.
You can climb onto walls using doors and bumpers.
Finishing a level is unlocking the next one.
ABOUT TILT CONTROL :
To get the best experience with the game which is using the accelerometer you must calibrate properly for each new ball! beware of the message which says:
“To ensure optimum control accuracy, hold device level, or slightly tilted towards and touch screen to start”
You can also re-calibrate at any time by pressing pause and resume.
Marball Odyssey,
